I have the Tamron 90mm macro. It won't accept commands for focus. It acts like the lens is set to manual.This lens does not have a switch for auto/manual, it is a push/pull mechanism.My Sigma 150 and Nikkor 60 work just fine.Any info on compatibility with the Tamron 90 would be appreciated.This is mounted on a Nikon D700.

I too have had problems with the Tamron 90 macro. I have the Nikon D7000. It would move with the remote program but ir would not return to the first focus point. It was always out of focus. I too will change to a Nikon 105 micro as I suspect the tamron as much as I like the glass, does not like helicon remote. It does work well as just a micro lens on the camera. Too bad as the price was right

It appears I have an issue with the lens. This is a push/pull Auto/Manual focus. I notice that getting it to auto focus sometimes requires multiple push pulls. I think it is defective and luckily still under warranty.

I was actually able to get it to cooperate with Remote. But I will probably be sending it in for repair.

How did you actually managed it? I just bought a 2nd hand Tamron SP AF90mm 2.8 DI (272EN II) and operation with HR is a pain. Autofocus works sometimes but I cannot move the focus in small steps. When pressing the arrow keys in HR the focus jumps only once in either direction. No way to properly set a and b point. Is it a bug or a feature of this Tamron lens. I've noticed that some user in this forum had mixed results with this lens. Thanks for any suggestion/help.F.K.

I wish I had a definitive answer for you. I notice that in just handheld use, sometimes the lens won't focus when set to auto. It is like a contact is dirty or something, but cleaning the contacts has no effect on the issue.

When it is focusing using Remote, I sometimes have to use the <<< and >>> to kind of shake it loose. Live view which does not stop down makes it tough to visualize the focus points as well. Live view image can appear so overexposed that it is difficult to see any actual change in focus step to step.

Problem solved! After talking with the local (german) Tamron Support I've send the lens to them and received it back in less than a week. It's now fully working either with Camera Control Pro 2 and Helicon Remote. YES!While the lens was in repair I've found out that many current Tamron (and also Sigma) lenses can't properly autofocus in LiveView. Some users mentioned that this can be fixed with a lens firmware upgrade. Great customer service by Tamron: They've charged me nothing for "autofocus correction" even though my lens was quite a while out of warranty.
